Rolling device for producing insulating pipes {The device for rolling}

The present invention relates to a rolling device for producing insulating pipes, and in particular, by applying a binder (adhesive or adhesive) to the upper surface of a thin glass fiber mat automatically and winding it on a forming roller to heat insulating pipe of a predetermined thickness and a predetermined diameter. The present invention relates to a rolling device for producing insulating pipes that can be easily manufactured to facilitate the binder process and the winding process of the insulating pipes.

In general, pipes such as cooling and heating facilities of power generation and petrochemical plants, cooling and heating facilities of industrial equipment, cooling and heating facilities of various manufacturing equipment, and heating and cooling facilities of air conditioning equipment are used for insulating materials of various sizes and materials. Insulation materials (hereinafter referred to as 'insulation pipes') are installed to block heat exchange with the outside through the piping to achieve energy savings and cost reduction.

In recent years, in order to reduce manpower and improve productivity, the insulation pipes are made through automation lines when installing (installing) these pipes. The insulation pipes can be automatically inserted into the pipes. Standardization is required.

Insulation pipes currently being produced are press-molded with short (short fiber) glass fibers in a molding mold, and incomplete insulation pipes with one side cut to form a mold and demoulded are joined to obtain a cylindrical finished product. In this case, it is impossible to manufacture a complete cylindrical insulation pipe, and if it depends on the press molding, due to the bulkyness of the short glass fiber itself, the binding strength of the tissue is weak and the rigidity is low, and the density is very low compared to the product thickness.

In addition, according to the diameter of the insulating pipe is required to form a separate mold, the production cost is excessive, and the density of the insulation pipe is low, the thermal insulation efficiency is greatly reduced, even if manufactured to a predetermined standard using a molding mold to cut naturally occurring Due to the deformed easily, there was a problem that can not stand the standardized product, the obstacle to automation.

In addition, when the insulation pipe is constructed, it is inserted into a cooling / heating tube using one incision and then finished by taping the outer surface thereof, which causes troublesome installation work and requires a lot of installation time.

The present invention has been invented to solve the problems of the prior art as described above, by producing a glass fiber by a method such as needle punching, and by winding a relatively thin glass fiber mat to a forming roller to insulate a predetermined thickness and a predetermined diameter By manufacturing pipes, manufacturing costs are reduced, the strength is greatly improved, and high-density insulating pipes having excellent heat insulating properties can be formed, and the drawing, conveying, binder application, pressure winding, By making a series of work processes such as cutting, the work process and lines are greatly reduced, the automation and standardization are achieved, the productivity is greatly improved, and the insulation pipe is made by diagonally cutting to maintain the wide cutting surface when cutting the glass fiber mat. Jaw does not occur at the beginning and end of the odor, and pressure control at one end of the forming roller By installing an additional pressure roller to pressurize the glass fiber mat to be wound, a large amount of binder penetrates into the glass fiber mat to obtain a high-density heat insulation pipe with greatly improved adhesive strength, and a binder is coated on the outer circumferential surface of the heat insulation pipe. Its purpose is to provide for closure.

In order to realize the above object, the present invention is a rolling device for producing a heat insulation pipe for producing a heat insulation pipe of a predetermined thickness, a predetermined size and a predetermined length by applying a binder to the upper surface of the glass fiber mat, the pressure winding. A supply roller for supplying a glass fiber mat to a rear portion of the rolling device for manufacturing the heat insulation pipe and having a roller member formed at left and right sides of the supply roller, and a transport unit for transporting the glass fiber mat drawn out from the supply unit to the square; And a first binder supply part provided with an application roller for applying and conveying a binder on an upper surface of the glass fiber mat conveyed from the conveying part, and having a first binder box for supplying a binder to the application roller surface. Winding the glass fiber mat coated with the binder several times by the binder supplying part, A forming roller for forming a pipe, a driving shaft and a driven shaft for rotating the forming roller, and a pressing roller for applying a binder to the outer circumferential surface of the glass fiber mat while pressing the glass fiber mat wound on the forming roller are installed and pressurized. A second binder supply part including a second binder box for supplying a binder to the surface of the roller, a pressure adjusting part for adjusting the pressure at which the glass fiber mat is wound by lifting the second binder supplying part, and a pressure of the pressure adjusting part. When receiving the glass fiber mat wound on the forming roller is wound to a desired length provides a rolling device for producing a heat insulation pipe, characterized in that it comprises a cutting portion which is cut diagonally so that the cutting jaw is not formed.

The present invention is to apply a binder to the upper surface of the glass fiber mat to be transported by pressing the winding roller to produce a high-density cylindrical insulation pipe to reduce the manufacturing cost, excellent insulation effect and obtain a standard product, one insulation pipe Since the whole series of work is performed in the manufacturing apparatus, the manufacturing line is greatly reduced, and automation and standardization are achieved, which greatly increases productivity.

In addition, in the prior art, since the worker manually cuts the glass fiber mat by using a cutting tool, productivity decreases due to fatigue accumulation and musculoskeletal disorders are generated. Productivity is improved by precisely cutting the wire, and when cutting the glass fiber mat, the cutting edge is precisely cut in an oblique direction using a circular cutter, so that stepping is not generated at the winding end of the insulation pipe, and the winding of the glass fiber mat starts. Since the part is also an oblique cut surface, there is an effect that can produce a high-quality product that does not generate step even in the inner circumference of the insulation pipe.

In addition, in the present invention, when forming the glass fiber mat by pressing the coating on the upper surface while applying a binder, as well as the chemical bonding between the glass fiber mat wound in multiple layers as well as the physical bonding is increased by the pressing force of the pressure roller glass fiber at high temperatures There is an effect of extending the service life because the bond between the mat is not broken.

In addition, the insulating pipe of the present invention has an effect of obtaining a product without the risk of deformation unless an artificial external pressure is applied since the density is increased by pressurization during molding and there is no stepped cylindrical shape.

Meanwhile, as shown in FIG. 6A, the cutout 200 extends upward from the top of the rolling device 1 for manufacturing the heat insulation pipe so that a side plate 205 is formed and parallel to the side plate 205. A pair of guide rods 206 are fixedly installed, and a movable body 207 coupled to the outer periphery of the guide rods 206 is installed to move along the guide rods 206, and a drive shaft rod parallel to the side plate 205 ( 208 and a driven shaft rod 209 are installed, a chain gear 210 is installed at one end of each of the driving shaft rod 208 and the driven shaft rod 209, and the chain 211 is connected to the chain gear 210. ) Is combined.

Coupled with the chain 211 and the chain attachment 212 is fixed to the upper side of the moving body 207, the stationary motor 213 is fixed to the side plate 205 of the right side drive shaft 208 and the driven shaft rod ( 209 is connected to the power transmission means 214.

An inverter motor 215 is installed on the movable body 207, and the connecting plate member 216 is fixed to the lower end inclined portion of the movable body 207 to be inclined at a predetermined angle D.

The shaft member 217 is fixed to the center of the connecting plate 216 and the power transmission means 224 for connecting the inverter motor 218 and the rotary shaft 219 of the shaft bar 218 of the shaft member 217 is configured The circular cutter 201 is fastened to the bottom fastener 220 of the shaft bar 218.

Left and right side limit sensor 221 is installed to prevent excessive transfer of the movable body 207, and is fixed to both sides of the chain 214 is composed of a moving member 222 to recognize the limit sensor 221, The inclination angle D of the connecting plate 220 and the circular cutter 201 is installed to be inclined at an angle of 6.8 ° in the discharge direction of the glass fiber mat 2 as compared to the horizontal line.

The inclination of the diagonal cut surface P by the circular cutter 201 is also maintained at 6.8 ° slope.

Each of the limit sensors 221 is configured as a pair so that when the moving object 207 approaches the inner limit sensor 221, the speed is rapidly decelerated, and when the moving object 207 approaches the outer limit sensor 221, the limiting sensor 221 is stopped. .

The material of the circular cutter 201 is that the edge of the general knife, that is, the diamond is electrodeposited on the cutting blade portion to prevent wear even if used for a long time, so that the blade does not become blunt.

In the present invention, the glass fiber mat 2 is formed by diagonally cutting the diagonal cut surface P having a length (width) of about 6 to 10 times the thickness T of the glass fiber mat 2, as shown in FIG. Since the stepped portion of the winding end is removed by the diagonal cutting surface P, the start portion and the end portion of the formed insulation pipe are smoothly processed without the stepped portion.

In addition, although it differs according to the thickness T of the glass fiber mat 2, when it is 15 mm thickness T, the diagonal cut width L becomes about 100 mm.

As shown in FIG. 8, the recessed groove 203a and the inclined surface 203b are formed on the auxiliary plate 203 so as to accommodate the edge portion of the circular cutter 201. The inclination of the inclined surface 203b is equal to or similar to the inclination angle D of the circular cutter 201.

Therefore, the upper surface of the glass fiber mat (2) is maintained in a flat unfolded state by the auxiliary roller 202, so that when the glass fiber mat (2) is cut, swelling or skewing of one side of the glass fiber mat (2) This is prevented, and the auxiliary plate 203 serves as a cutting plate of the glass fiber mat (2). That is, not only the sagging of the glass fiber mat 2 but also plays a role of guiding when the circular cutter 201 moves.

The rod end of the air cylinder 204 is fixed to the lower portion of the auxiliary plate 203 can be elevated. For example, during the period in which the glass fiber mat 2 is moved and molded, the auxiliary plate 203 is lowered by the air cylinder 204 as shown in FIG. 6 to ensure smooth movement of the glass fiber mat 2, and the circular cutter 201. During the period in which the glass fiber mat 2 is cut diagonally by the air cylinder 204, the auxiliary plate 203 is raised by the air cylinder 204, and the glass fiber mat 2 is flat and evenly spread under the cooperation of the auxiliary roller 202.

In this state, as shown in (b) of FIG. 6, power is supplied to the forward / reverse motor 213 of the cutting part 200 located on the outer side of the glass fiber mat 2 so as to rotate forward and at the same time to the inverter motor 215. Power is supplied to the circular cutter 201 is rotated.

When the forward and reverse motor 213 rotates forward, the chain 211 rotates in the counterclockwise direction, and the movable body 207 moves forward in the direction of the driving shaft rod 208 by the chain attachment 212 coupled to the chain 211. The glass fiber mat 2 is diagonally cut by the circular cutter 201 installed in the movable body 207.

In addition, the moving body 207, which has diagonally cut the glass fiber mat 2, continues to move, and when the moving member 222 approaches the limit sensor 221, the forward / reverse motor 213 and the inverter motor (by the controller 600). The power supplied to the 215 is cut off, the movable body 207 is stopped and the rotation of the circular cutter 201 is stopped.

At the same time as the moving body 207 stops, reverse power is supplied to the reverse motor 213 to reverse rotation, the chain 211 rotates clockwise, and the moving body 207 moves backward in the direction of the driven shaft rod 209. When the moving member 222 coupled to the chain 211 approaches the limit sensor 221, the power supplied to the stationary motor 213 is cut off until the next oblique cut and the moving body 207 is stopped. . In addition, the circular cutter 201 rotates only during the forward movement period for cutting the glass island mat 2.

In the present invention, the drawing length or the conveying length of the glass fiber mat 2 measured by the encoder 700 is compared with the reference molding length set in advance by inputting the controller 600, and the controller 600 if the reference molding length is matched. By the rotation of the transfer unit 20 is stopped, when the transfer of the glass fiber mat 2 is stopped in this state by the operation of the cutting unit 200 in the glass fiber mat (2) as shown in (b) of FIG. Diagonally cut to wide width.

In the present invention, the inclination angle (D) of the circular cutter 201 has been described as 6.8 °, but can be appropriately added or subtracted according to the situation. For example, the temperature may be adjusted by 5 ° to 10 ° based on 6.8 °.

By the inclination angle (D), the glass fiber mat (2) is obliquely cut at 6.8 ° slant, and finally the stepped to the outer circumferential surface of the insulation pipe is finally bonded to the surface of the glass fiber mat (2) on which the diagonal cut surface (P) is wound. Does not occur.

When the diagonal cutting of the glass fiber mat 2 is completed, the remaining glass fiber mat 2, which is diagonally cut, is transferred, and a binder is applied to the diagonal cutting surface P by the pressure roller 81, and the forming roller 40 Pressurized winding completes the molding. In this case, the diagonally cut glass fiber mat 2 is transferred to the attachment part 70.

When the molding is completed, the operator operates the air cylinder 61 while holding the molding roller 40 whose rotation is stopped, and moves the driven shaft 60 back, so that the molding roller 40 is driven by the driving shaft 50 and the driven shaft ( Separated from 60), the forming roller 40 is moved to a drying chamber or a drying process to dry, finish and pack.

Then, the glass fiber mat (2) is coupled to one side of the new forming roller 40 is not odor to the drive shaft 50, by operating the error cylinder 61 to move the driven shaft 60 to the new forming roller The other side is combined and the installation is completed.

When the installation of the new forming roller 40 is completed, the glass fiber mat 2 transferred to the attachment portion 70 is deposited on the forming roller, and is repeatedly wound in the process of pressing, shaping and cutting the insulating pipe. Mass production is possible.

Since the initial winding portion of the glass fiber mat 2 wound on the forming roller 40 is coated with a binder 900 and is an oblique cut surface P, stepping does not occur not only on the outer circumferential surface but also on the inner circumferential surface of the insulation pipe.

According to the present invention, the entire process is performed by reducing each process that has been conventionally spread or dispersed in one manufacturing apparatus, so that the manufacturing line is reduced, workability and productivity are improved, and the installation space is naturally reduced.
